Use Facebook or Call of Duty account login: Sadly there's no username/password login, you have to use Facebook, your Call of Duty Activision Account or play as a guest. To get the best from CoD:M you need your phone running as best it can. Shut down background activities and alerts: If you have a gaming mode on your device then now is the time to use it to reduce notifications you don't want and to kill other processes that might be lowering the performance of your phone. If you're right at the limit, your phone won't run as well, and this is a demanding game. Prepare device storage: You'll need around 1.6GB of storage to install CoD: Mobile and for game data, so you might have to clean something out.
